AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
230 PM CDT WED MAY 10 2006

.DISCUSSION...
FRONT CURRENTLY LOCATED FROM CROCKETT TO BRENHAM MOVING SOUTH AT
AROUND 25 MPH. APPEARS CONVERGENCE ALONG THE BOUNDARY IS ASSISTING
THE CAP ERODE AND BROKEN LINE OF PRECIP IS DEVELOPING ALONG THE
BOUNDARY. EXPECT IT TO FILL IN AND FURTHER INTENSIFY AS IT
APPROACHES THE COAST. ATMOS AHEAD OF THE FRONT IS POTENTIALLY
EXTREMELY UNSTABLE WITH CAPES >5000 AND LIS -7 TO -11. SEVERE
STORMS ARE LIKELY WITHIN THE LINE WITH HAIL AND DAMAGING WINDS BEING
THE PRIMARY THREAT. ASSUMING CURRENT MOVEMENT HOLDS...ANTICIPATE THE
LINE TO BE FROM ROUGHLY MOSS HILL TO DOWNTOWN HOUSTON TO EL CAMPO
AROUND 430PM AND OFF THE COAST EARLY THIS EVENING. IMPROVING
CONDITIONS AND COOLER TEMPS POST FROPA TONIGHT.

VERY NICE WX ON TAP FOR THE MAJORITY OF THE NEXT 7 DAYS. SFC HIGH
PRES WILL MOVE EAST OF THE REGION LATE FRIDAY ALLOWING AN ONSHORE TO
RESUME FRI ALONG WITH A BRIEF WARMING TREND. MID LEVEL TROF BECOMES
ANCHORED OVER THE EASTERN US AS RIDGE BUILDS ACROSS THE ROCKIES.
THIS FAVORABLE UPPER LEVEL PATTERN SHOULD ALLOW ANOTHER FRONT TO
MOVE THROUGH ON SUNDAY. DOUBT THERE WILL BE ENOUGH TIME TO GET MUCH
MOISTURE BACK INTO THE AREA PRIOR TO THE FRONT ARRIVING...SO WILL
MAINTAIN THE LOW POPS ALREADY IN THE FCST IN ASSOCIATION WITH THE
FROPA. NW FLOW ALOFT SHOULD PERSIST INTO THE MIDDLE OF NEXT WEEK
WHICH WILL PROVIDE DRY CONDITIONS WITH OVERNIGHT LOWS IN THE UPPER
50S-LOW 60S AND AFTN HIGHS BETWEEN 80-85. 47

&&

.MARINE...
FRONT WILL APPROACH EARLY THIS EVENING USHERING AN OFFSHORE FLOW
WHICH WILL STRENGTHEN BY LATE EVENING/MIDNIGHT. WE WILL CONTINUE SCEC
FOR WATERS EARLY EVENING...THEN SCA OVERNIGHT. WAVE HEIGHTS SHOULD
PICK UP 7-8 FEET SOUTHERN FRINGES OF COASTAL WATERS BY TOMORROW
MORNING. WAVE HEIGHTS FALLING MID/LATE MORNING THURSDAY WITH
OFFSHORE FLOW DECREASING IN STRENGTH AND BECOMING NORTHEAST. ONSHORE
FLOW RETURNING LATER FRIDAY. NEXT FRONT MOVING ACROSS CWFA SATURDAY
NIGHT AND AGAIN EXPECT OFFSHORE FLOW ON SUNDAY. 37

&&

.AVIATION...
CEILINGS RUNNING NEAR 3KFT CENTRAL AND SOUTHERN PART OF CWFA. HAZE
STILL RESTRICTING VISIBILITIES IAH AND TO A LESSER EXTENT HOU.
BELIEVE THIS WILL IMPROVE AS WIND VEERS TO WEST/NORTHWEST
W/PRE-FRONTAL FRONT APPROACHING. FRONT SHOULD APPROACH IAH AROUND 4
PM AND SHOULD BE MOVING ACROSS COASTAL WATERS DURING THE EVENING.

5000 J/KG TO EAST OF CWFA AND OVER 7000 J/KG TO THE SW (CRP). MODEST
